B&R 8LSA55 EB030D1000

الوصف

The B&R 8LSA55.EB030D1000 is a synchronous servo motor from B&R’s 8LS series. This motor is part of a larger frame size compared to the 8LSA44, indicating higher performance capabilities. It’s designed for demanding, high-precision, and dynamic motion control applications in industrial automation.

B&R 8LSA55.EB030D1000: Synchronous Servo Motor (Size 5)

This part number specifies a particular configuration within B&R’s 8LS synchronous motor series. These motors are characterized by their compact design, high power density, and excellent dynamic performance. The “55” in the part number indicates a larger frame size (Size 5) than the “44” models, which translates to higher torque and power.

Key Specifications and Features:

• Type: Synchronous Servo Motor
• Manufacturer: B&R Automation (now part of ABB)
• Series: 8LS
• Frame Size: Size 5 (indicated by “A55”), which is a larger motor compared to the “44” models. This typically corresponds to a centering diameter of 130 mm for mounting.
• Rated Speed: 3000 RPM (revolutions per minute).
• Nominal Torque: Approximately 11.6 Nm (Newton-meters).
• Stall Torque: Approximately 12.5 Nm.
• Nominal Current: Around 7.1 Amps.
• Stall Current: Around 7.7 Amps.
• Nominal Power: Approximately 3644 W.
• Maximum Torque: Can reach up to 41.4 Nm.
• Maximum Current: Up to 33 Amps.
• Maximum Speed: Can reach up to 9000 RPM.
• Voltage: Typically operates at 400 V.
• Shaft: Smooth shaft, meaning it does not have a keyway or spline.
• Connectors: Features angled swivel connectors, providing flexibility for cable routing.
• Brake: The “EB” in the part number indicates it does not include a holding brake.
• Protection Class: IP64, indicating it is protected against dust ingress and splashing water from any direction.
• Cooling: Self-cooling (construction type A), relying on natural convection for heat dissipation.
• Pole Pairs: Typically 4 pole pairs.
• Feedback System: The “D1000” refers to the encoder system. For 8LS motors, this typically signifies an EnDat multi-turn encoder, providing highly precise position and speed feedback, often with a high resolution (e.g., 19-bit or 25-bit for absolute position, eliminating the need for homing procedures and batteries).
• Embedded Parameter Chip: B&R 8LS motors come with an embedded parameter chip within the encoder that stores all relevant mechanical and electrical information. This enables the paired B&R ACOPOS servo drive to automatically identify the motor and configure itself for optimal control, simplifying commissioning.

Decoding the Part Number:

• 8LS: Denotes the 8LS Synchronous Motor series.
• A55: Specifies the motor type and dimensions (self-cooled, flange-mounted, Size 5).
• EB: Indicates the connection type and absence of a brake (angled swivel connectors, no brake).
• 030: Relates to the nominal speed (3000 rpm).
• D1000: Specifies the integrated feedback system (EnDat multi-turn encoder).
• 

Typical Applications:

Given its higher power and torque compared to smaller 8LS models, the B&R 8LSA55.EB030D1000 is suitable for more demanding applications in industrial automation, including:

• High-Speed Packaging Machinery: For applications requiring rapid and precise movements of heavier loads.
• Machine Tools: In CNC machines for axes that require significant torque and high accuracy.
• Robotics: In larger robotic arms or applications where high payload capacity and dynamic response are crucial.
• Material Handling Systems: For conveyors, gantry systems, and automated storage and retrieval systems moving heavier items.
• Printing Industry: In presses requiring strong and precise web tension control or print head positioning.
• Converting Machinery: For unwinding, winding, cutting, and other processes where consistent tension and speed are critical.
